I did same with HP laptop from famous NVIDIA crap.
I did purchase new motherboard from usa.
Then while installing,realised that great NVIDIA had burnt the thermal pad and it made its indent on even copper bottom of heatsync.
I will post link when I get full pc.
Right now I am living totally without laptop or desktop for last week or so.
Happy with my ATRIX and focus.
Both work wonders together.
